That signature doesn't check out for me, are you sure you didn't edit the message at all after signing?
it doesn't matter. it's the owner of 1A7RdYVo6rVmPXLHeeHqnTym7otCNmCDPb saying he owns 1BPFKnxAENaxp26g8QbWKUWMuedRo5ZjDY, not the other way around.
though looks like someone is willing to send to the old address. which is fine, I think.
Sending to the 1BPFKnxAENaxp26g8QbWKUWMuedRo5ZjDY address should be fine, but his signed message should be coming from 1BPFKnxAENaxp26g8QbWKUWMuedRo5ZjDY as well (
posted in September last year by letyouearn here ). He's trying to sign a message from 1A7RdYVo6rVmPXLHeeHqnTym7otCNmCDPb, which hasn't been used before by this account as mentioned by another user, so there's no proof that the account is in the hands of the original owner still.

Here is the Unedited Post you are looking for. Please verify it and tell me if its ok for you.
That one seems to verify, but like I mentioned above, it doesn't prove that you're the original owner of this account. If you have access to the private key for 1BPFKnxAENaxp26g8QbWKUWMuedRo5ZjDY still (which you said you did a couple posts ago), why not sign the message you posted above with the address 1BPFKnxAENaxp26g8QbWKUWMuedRo5ZjDY to prove that you're the original owner of the account?
